A cement factory collapsed in Bangladesh, killing two people, with several workers feared trapped, a police official said on Thursday. Two bodies were pulled from under the roof of the collapsed factory in the port town of Mongla, 335 km (210 miles) southwest of the capital, Dhaka, district police official Nizamul Haqu Mollah said. "We are not sure how many workers were there, but our recovery efforts are continuing with the help of the fire brigade," Nizamul, a police superintendent, told Reuters by telephone. The firm was a subsidiary of the Bangladesh army, he added.
